There is pretty much big amount of guides of "Division layouts", but little to no guides about unit layouts - especially layouts of tanks (with "No step back" DLC), as their characteristics can be very different (example - medium tanks can be "beefed up" to level of super-heavy tank). Also, old glitch what allowed to get tons of equipment (by sending exact 2400000 units lend-lease and spending it on planes and converting entire army into tank and mechanized divisions), without new glitches main characteristic is cost-efficensy.

Light tanks as purely support in templates with some upgrades seem to tear through SP AI's builds. It's basically budget space marines
